WINDOW.

SPECIFICATION forming part of Letters Patent No. 786,213, dated March28, 1905.

Application filed July 18, 1904. Serial No. 217,078.

To ctZZ whom it may concern.-

Be it known that I, W ILLIAM J. HEIM, a citizen of the United States ofAmerica, residing at Butler, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements inWindows, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention has relation to windows, and more particularly to theshades; and the object of this invention is to provide a novel form ofwindow shade, which is arranged within the frame and may be adjusted toany position desired without interfering with the operation of thesashes carried by the frame.

Briefly described, the parts constituting my invention are constructedand arranged in the following manner: Within the top part of the frame Iprovide a shade-roller, upon which is secured a shade or screen, and inthe jambs of the window I provide racks, in which the looking mechanismcarried by the shade or screen is adapted to engage, this lockingmechanism being so constructed that the shade or screen may be raised orlowered and locked in any desired position.

All of the above construction will be hereinafter more fully described,and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical transversesectional view of a window-frame, showing my improved shade-curtainmounted therein. Fig. 2 is a vertical sectional view of the window-frameas constructed in accordance with my invention.

To put, my invention into practice, I construct a frame which comprisesside boards 1 1, a sill 2, and a top board 3. Between the top board andthe sill of the frame are mounted jambs 4 4, which form weight-wells 55, and between the jambs 4 4, and preferably near the top of the frame,is a horizontal partition 6. This partition forms a compartment'l', andin the compartment is mounted, between the jambs 4 4, a shade-roller 8,the shaft 9 of which protrudes through one of the jambs into theweight-well 5 and carries on its protruding end a pulley 10, to which isattached a rope 11, carrying a weight 12. Upon each of the jambs 5 ismounted a weather-strip 15, and mounted between the jambs 4 4 are thesashes 17 18. The reference-numerals 19 19 indicate racks, which areformed integral with the jambs 4 4.

Upon the roller 8 is mounted a shade or screen 20, which carries uponits lower end a casing 21, this casing extending the entire width of theshade or screen, and is preferably made rectangular in shape. Within theeasing is mounted a locking mechanism, which comprises rods 22 22, theserods being slidably mounted in brackets 23 23, and bushings 24 24, thebushings being carried in each end of the casing, and in these bushingsare mounted springs 25 25, one end of the spring being at- 5 tached tothe rod, while the other end thereof is attached to the bushing. Theends of the rods, which extend inwardly, pass through brackets 23 23 andare bent out of alinement with the rest of the rod, as clearlyillustrated 7 0 in Fig. l of the drawings. On the confronting faces ofthe ends of these rods 22 22 are formed teeth 26 26, which are adaptedto mesh with the pinion or star-wheel 27, that is rotatably mountedwithin the casing 21, and the shaft ofthis wheel or pinion extendsoutwardly upon the one side of the casing and has connected to its end aknob 28. To adjust the curtain, the knob 28 is rotated, imparting arotary movement to the wheel or pinion, and as this wheel meshes withthe teeth carried by the rods 22 22 each rod will be drawn inwardly,compressing the springs 25 25, and when the ends of the rods 22 22 havebecome disengaged from the racks 19 19 the weight 12, mounted 5 in oneof the weight-wells 5, will descend, revolving roller 8 and causing thesame to wind the curtain or screen thereon. Upon the knob being releasedthe springs 25 25 expand, forcing the ends of the rods 22 22 in toengagement 9 with the rack.

What I claim is- The combination with a window-frame, of racks providedwith inclined ratchet-teeth and carried by the jambs of said frame, acurtainshade mounted in said frame, means for automatically raisingsaidshade, and locking mech- In testimony whereof I afiix my signature inanism carried by said shade and adapted to enthe presence of twoWitnesses. gage said racks, said locking mechanism com- VILLIA-M J HEIMprising horizontally-disposed spring-pressed 5 rods having teeth ontheir inner ends, a pini Witnesses:
